No, but Mel also wouldnt run away from that categorization like Stapp did, either. Big difference. Its one thing to say "Im Christian, im a singer...classify me however you want" but an entirely different thing to say "IM NOT A CHRISTIAN BAND....ARGH!!!" like Scott did.
He was obviously not ashamed of being Christian, or he wouldn't have sung songs about God. He just didn't want the LABEL that categorizes them into one genre.
